Abstract (en)

[origin: EP0843211A1] A process for the sequential development in the same processor of imagewise exposed low silver and conventional photographic recording materials comprises: (i) developing the low silver photographic recording material in a redox developer/amplifier solution containing: a colour developing agent an oxidizing agent a buffering agent and having a pH in the range from 10.0 to 12.5 and then removing the oxidizing agent and (ii) employing the solution to develop a conventional silver photographic recording material. The order of steps (i) and (ii) may be reversed in which case after the development of the conventional photographic recording material in step (ii), an oxidizing agent is added to the solution and the solution used as a redox developer/amplifier solution in step (i). The peroxide is conveniently removed by the addition of a reducing agent such as a sulphite.
